WlRE NAIL AND DIE FOR POINTING THE SAME.

SPE CIPICATION forming pair. of Letters Patent No. 371,162, dated October 11, 1887.

Application filed June 9, 1887. Serial No. 240,725. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM G. ALGEO, a citizen of the United States, residing at Beaver Falls, Beaver county, Pennsylvania, have in- 5 vented certain new and useful Improvements in Dies for Pointing Nails, of which the following is a specification.

The object of my invention is to provide a new form of die adapted to compress the end of a wire nail while being fed through the nailmaking machine into a beveled point, the bevel of said point being preferably made from one side to the other across the longitudinal center, and thus leaving the other side 1 straight. One manifest advantage of such a nail is its absolute certainty of clinching on the same side,thus securing uniform fastening, whereas wire nails beveled from each side to ward the center may turn in clinching either to the right or left, and thus produce irregular fastening.

This die consists of two interlocking pieces of 1netal,one of which is provided with straight surfaces only, and the other with one inclined surface adapted to leave a beveled slot for forming a beveled point on the nail when said interlocking pieces come together.

One form of my improved die is shown in the accompanying drawings, in which-- 0 Figure 1 shows the two parts of the die together. Fig. 2 shows the two parts of the die separated. Fig. 3 is a section on line a: so of Fig. 1, showing the beveled opening. which points the nail. Fig. 4 is a top view of the die, the parts being separated. Fig. 5 shows the completed nail.

The same letters indicate similar parts in the various figures.

A and B indicate the two pieces of metal forming the die. These pieces are secured at their outer ends to the reciprocating machinery of the nail-making machine, and at the proper time are moved together, as shown in Fig. 1., the projections of B entering the de- 5 pressions in A. These projections and depressions exactly coincide and fit each other except in one place-that indicated by the open ing C, Fig. 3--where the edge of one part inclines toward the straight edge of the other to form a bevel corresponding accurately with the bevel given to the nail and only touching near the extreme edge of the die, where for a very slight distance an opposite inclination is given to both parts of the die, as shown by D in Figs. 1, 2, and 3.

The wire from which the nails are cut is fed through the machine in the direction from D to G, and the head has already been upset and shaped before the parts A and B are moved together. The exact time of the conjunction (o of A and B of course is regulated by the length desired for the nail; but when these two parts come together they force the metal, without clipping or weakening in any way, into the bevel, as shown in Fig. 5, corresponding with the beveled slot 0 in Fig. 3.

The operation and uses of my improved die are, I think, sufficiently obvious without further description, the bevel. as before stated, being such that the nail will always clinch in 7c the same direction.

I claim- 1. The abovedescribed die for pointing nai1s,which consists of two interlocking pieces of metahone of which is provided with straight surfaces only and the other with one inclined surface adapted to leave a beveled slot for forming a beveled point on the nail when said interlocking pieces come together, as herein described and shown. 8o

2. A wire nail formed with a beveled point extending from one side to the other across the longitudinal ceuter,and in which the opposite side of the nail is left straight, as and for the purposes specified.
